TCP IP Stack | Breaking Cybersecurity News | The Hacker News

As many as 13 security vulnerabilities have been discovered in the Nucleus TCP/IP stack, a software library now maintained by Siemens and used in three billion operational technology and IoT devices that could allow for remote code execution, denial-of-service (DoS), and information leak. Collectively called " NUCLEUS:13 ," successful attacks abusing the flaws can "result in devices going offline and having their logic hijacked," and "spread[ing] malware to wherever they communicate on the network," researchers from Forescout and Medigate said in a technical report published Tuesday, with one proof-of-concept (PoC) successfully  demonstrating  a scenario that could potentially disrupt medical care and critical processes. Siemens has since released  security updates  to remediate the weaknesses in Nucleus ReadyStart versions 3 (v2017.02.4 or later) and 4 (v4.1.1 or later). Primarily deployed in automotive, industrial, and medical applications, Nucleus ...

The US Cybersecurity Infrastructure and Security Agency (CISA) has  warned  of critical vulnerabilities in a low-level TCP/IP software library developed by Treck that, if weaponized, could allow remote attackers to run arbitrary commands and mount denial-of-service (DoS) attacks. The four flaws affect Treck TCP/IP stack version 6.0.1.67 and earlier and were reported to the company by Intel. Two of these are rated critical in severity. Treck's embedded TCP/IP stack is deployed worldwide in manufacturing, information technology, healthcare, and transportation systems. The most severe of them is a heap-based buffer overflow vulnerability ( CVE-2020-25066 ) in the Treck HTTP Server component that could permit an adversary to crash or reset the target device and even execute remote code. It has a CVSS score of 9.8 out of a maximum of 10. The second flaw is an out-of-bounds write in the IPv6 component ( CVE-2020-27337 , CVSS score 9.1) that could be exploited by an unauthentic...

Every week seems to bring news of another data breach, and it's no surprise why: securing sensitive data has become harder than ever. And it's not just because companies are dealing with orders of magnitude more data. Data flows and user roles are constantly shifting, and data is stored across multiple technologies and cloud environments. Not to mention, compliance requirements are only getting stricter and more elaborate.  The problem is that while the data landscape has evolved rapidly, the usual strategies for securing that data are stuck in the past. Gone are the days when data lived in predictable places, with access controlled by a chosen few. Today, practically every department in the business needs to use customer data, and AI adoption means huge datasets, and a constant flux of permissions, use cases, and tools. Security teams are struggling to implement effective strategies for securing sensitive data, and a new crop of tools, called data security platforms, have appear...
